Video picture play method, device and equipment and computer readable storage medium

Abstract

The invention discloses a video picture play method, device and equipment and a computer readable storage medium and belongs to the field of multimedia data processing. The method comprises the following steps: creating a virtual canvas according to a display area in a current page, wherein the position of the virtual canvas is matched with the position of the display area, the width of the virtual canvas is equal to that of the display area, and the height of the virtual canvas is equal to that of the display area; and for each frame of picture in a video, extracting the picture from the video and drawing the picture in the virtual canvas to realize play of the video picture, wherein the height of the played picture is equal to the height of the virtual canvas, and the width of the playedpicture is equal to the width of the virtual canvas. The method can realize a video play effect, and does not cause the case of blank area or overflow of the display area in either the horizontal direction or the vertical direction, thereby improving picture play effect and ensuring that the video can be played normally.

Description

technical field [0001] The invention relates to the field of multimedia data processing, in particular to a method, device, equipment and computer-readable storage medium for playing video images. Background technique [0002] With the development of data processing technology and the popularization of multimedia data, video has been widely used and disseminated due to its rich content, intuitive and vivid features, and strong interest. Playing video on the terminal has become a common function for users. The video screen needs to be played when the video is played. [0003] In related technologies, a video includes multiple frames of pictures, and each frame of pictures will be played sequentially in the display area of ​​the terminal when playing the video, and the aspect ratio of each frame of pictures is fixed. In order to fully play each frame of picture in the display area, the height and width of the picture can be proportionally scaled according to the size and aspe...

AI Technical Summary

Problems solved by technology

[0004] When the aspect ratio of the display area is not equal to the aspect ratio of the video screen, after the screen is proportionally scaled, if the height of the screen is equal to the height of the display area, a blank area will appear in the horizontal direction of the screen or overflow display area

Similarly, if the width of the screen is equal to the width of the display area, a blank area or overflow of the display area will appear in the vertical direction of the screen

The phenomenon of blank area or overflowing display area mentioned above will affect the playback effect of the screen, and then affect the normal playback of the video.
